when I query Virtuoso 6 on my local 32bit windows 7 using Jena in a loop, after some iterations I got this error ocasionally:

java.net.SocketException: No buffer space available (maximum connections reached?): connect

However I tried this solution, but It didn't solve. Also this error doesn't occur when I query remote SPARQL endpoint (dbpedia.org/sparql)

Is there any Idea?

  • Are all your components up to date? Latest [Virtuoso 6](http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VOSNews) (why not 7? [Commercial or Open Source](http://virtuoso.openlinksw.com/features-comparison-matrix/)?), [Virtuoso JDBC Driver, Virtuoso Jena Provider](http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtJenaProvider), [Jena](http://jena.apache.org/), [Java 8](http://java.com/), Windows 7 patches, etc? What's the code of your loop? Does it close each connection before moving on to the next? More detail is almost always better... – TallTed Sep 29 '15 at 18:50
